To identify frontend performance bottlenecks, measure page load times and rendering speed using Lighthouse and Web Vitals. This process isolates inefficient resource usage and large bundle sizes, providing actionable metrics to resolve slow application performance.

Optimizing React rendering speed and bundle size involves implementing React.memo, useMemo, and useCallback for efficient rendering, combined with tree shaking, code splitting, and dynamic imports to minimize JavaScript load times.

Fixing slow database queries requires resolving N+1 query patterns, adding appropriate database indexes, and implementing caching mechanisms. These strategies directly improve backend resource efficiency and reduce overall API response latency.

Use lazy loading and image optimization when experiencing slow page load times due to large assets. Converting images to modern formats like WebP and employing efficient loading strategies significantly reduces initial bundle weight and improves user experience.

You can improve your Lighthouse score by implementing code splitting to reduce bundle size and caching API responses to minimize network latency. These techniques target inefficient resource usage to create a faster, smoother frontend experience.
